Abstract:

Results of simulation of multichannel radiation propagation under conditions of thermal blooming are presented and correction of nonlinear thermal distortion on the base of the beam phase control is considered. The results show the dependence of correction effectiveness on the number of channels and on the precision of reference beam phase retrieval. An additional increase in the effectiveness is possible with adjustment of amplification in the channels of the optical system, i.e., with the use of amplitude-phase control of radiation.

Keywords:

adaptive optics, thermal blooming, multichannel radiation, phase conjugation, amplitude-phase control over the beam wavefront
